WARE-LEASING MACHINE.

Application iled April 27, 1914.

To all whom t may concern.'

Be it known that l', CHARLES D. LANNINo, a citizen of the United States, and a resident of Boston, county of Suffolk, State of hlassachusetts, (whose post-oiiice address is 95 Milk str et, Boston, Massachusetts,) have invented an Tmprovement in Warp-Leasing Machines, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates particularly to warp-leasing machines intended for Inechanically leasing a warp and particularly, though not exclusively, a new warp which it is desired to have leased prior to its insertion in the loom.

The invention may be best understood by reference to the following description when taken in connection with the accompanying illustration of one specific embodiment thereof, while its scope will be more particularly pointed out in the appended claims.

chine to be described may be arranged in other relations than those set forth, and while the details thereof may be widely varied from those disclosed in the herein specific and illustrative form of machine, there is here provided a carriage sustaining a reciprocatory warp drawing needle and operating mechanism therefor, which carriage is caused to advance progressively lengthwise the machine to traverse the warp, the latter being maintained with its threads under tension and arranged in substantially parallel alinement. rlhe advancing needle is caused to seize the foremost warp thread and to draw the same between suitably positioned lease members, these being herein in the form of flexible cords held at their opposite ends with the required degree of tautness.

Means are provided to coperate with the needle to strip the drawn thread therefrom and to thrust aside the leased threads from the line of needle action. At suitable times and herein between each successive thread drawing, the relation of the leased cords is shifted by guiding and holding means which are mounted on the needle carriage and travel therewith so that in the described machine the successive threads are left reversely arranged between the lease members.

Referring to the drawings and to the illustrative embodiment of the invention, there is provided a suitably supported bed. or frame l carrying the end frame members 2, 2, which serve as supports for the warp carriage, lease members, and other parts.

The warp is sustained during the operation of the machine in a warp carriage or holder of any suitable construction, but which here comprises a pair of end frame members 3 one only of which is shown in Fig. 2). These are suitably connected to constitute a warp carrying frame generally similar to that shown in British patent to Brooks No. 4,661 of 1904, and provided with the upper and lower clamping jaws 4 and 5 respectively. The carriage is supported by oppositely extended hanger rods 6 resting on roller supports 7, being thereby maintained for longitudinal adjustment lengthwise the machine. The frame members are also provided with lower supporting rods 8l which the weight of the carriage causes to press against vertically disposed rollers 9 on the stationary frame of the machine. The

shaft 12 and thence downward and out` wardly to the second clamp bar 13 wherein they are tightly held and thence down to the loom beam, the warp thus having its threads supported in angular formation with the separatingv shaft 12 at the apeX of the angle. The upper clamping jaws .4 are adjustably mounted upon supporting ro ds 14 so that they may be adjusted to put the necessary tension upon the threads over the separator shaft.

The drawing needle is mounted upon a carriage 21 which latter is adapted to slide lengthwise the machine and transverselyT the warp lupon suitable guide-ways formed on the bed of the machine. During the travel of the carriage the needle is given a reciprocatory movement to and from the threads of the warp. The construction of the needle carriage, the traversing mechanism therefor, and needle operating and thread stripping mechanism is substantially the same as that shown in prior patent to Fielder" al., No. 871,680,- dated November' 19, 1907, and need only be briefly referred to. To advance the carriage the latter is provided with a depen ding nut 22 (Fig. 2) engaging the constantly driven lead screw 23. rlhe lead screw is driven from the main drive shaft by gearing not hereinv shown. The moving parts on the needle carriage are driven from a countershaft 25 carried thereon through a.

gear 26 mesliingwith a drive pinion 27the latter splinedl on the drive shaftv 24 and traveling with the carriage. The needle is reciprecated by a link 28 having jointed connection-to a pivoted arm29, the latter in turn being oscillated by a link 30 connected to the crank disk 31 rotated'by the needle drive shaft 32. rlhe latter is driven by the rfhe needle slides in a sleeve or cylinder 34 and is given a partial turn on its advance and retraction by devices not herein disclosed, but which include a pin upon the needle engagingv a partially spiraled slot in the sleeve. The movement of the needle is so timed thatitiundergoes one complete reciprocation as the carriage is advanced a space corresponding approximately to the spacing between successive warp threads.

, Acting in advance of the needle and herein progressively advancing with the carriage, there is provided threadL separating means for selecting and separating the foremostwa-rp vthreads andpositioning a thread in the needlepath for each threaddrawing. Hereinsuch thread separating device is in the: form ofa sleeve member splined upon the driving shaft'12 the latter journaled in the frame of the machine and driven from 'the path of the needle..

The spirally. grooved sleeve 46 can be angularly` adjusted upon the sleeve member 40. For this purpose the sleeve 46 terminates in a` flanged portion 47 having a recess in which there is adapted t0 .seat the pin 48 slidably mounted inthe collar 49,thelatter being fast to the sleeve 40 by means of the set screw shown in Fig. 9. The opposite end of; the pin 48 is threaded intoa disk 51 which latter isnormally heldl close against the facevof: the collar 49 by the stud 52. The latter has one end threaded into-the collar but is' provided with a head 53y sliding in a' recess in the collar, a spring being inten-` posed between'the head. and: the bottom of. the recess yieldingly to force the collary into thel position shown. f

The collar, however, may be drawn to the left (as .viewed in Fig. 8) withdrawing the pin 48 from the Bange of the sleeve 47 whereupon thelatter may be turned, thereby to adjust the lip of the screw or helixl in different angular positions about the shaft. The flange 47 may be provided with a plurality of' recesses distributed circumferentially-about the same to permit of different positions ofadjustment of the pinB? 6.

rllhe collar 49 is circumferentiallygrooved as shown in Figs. 7 andv S and rests by its groove in the hook-shaped bracket 54 (Figs.` 1 and 2) which latter is carried'by a bent arm 55 fastenedto an upright support56 carried by the traveling needle carriage 21, so that the separating worm advances progressively across the machine always in fixed relation to the needle, but being turned in suitably timedrelation to present a thread for each thread drawing.

The 'free end of the thread, after being drawn between the leasing members as hereinafter described, is drawn I through a threadguide eye 6() formed'in the thread-guide 61 carried on the upright support 62A on the needle carriage `andhaving an open slot 63 (Fig.` 1) inclined'obliquely down and away from the direction of travel'of the carriage- YWhen drawn,'the thread end` is stripped from the needle and down and out' ofthe thread guide slot by the swinging stripper arm 64 which sweeps down andA across' the path of the needle immediatelyl following theY retractile movement ofthe latter. A thread deflector 65 alsoassists in throwing the drawn-in thread farther away from the needle carriage and the operating mechanism thereon.

The stripper arm 64 is slidably mounted in a sleeve 66 pivoted on the frame at 67 and is given a reciprocatory movement like that of a connecting rod through its connection to the crank disk 68. The latter is driven by the shaft 69 turned through the bevel gear 71, the latter carried upon the needle drive shaft 32, the proportions of the gears being such that the stripper is caused to execute its stripper movement upon each retraction of the-needle.

The threads when engaged by the needle are drawn between suitably positioned lease members. rlhese may be of any desired number and arranged for any required movement, but in the described machine they consist of a pair of flexible leasing members, herein in the form of cords 7 5 and 76, and the separately movable, intermediate lease member, herein in the form of a cord 77. The cords are'each arranged parallel with the travel of the needle lengthwise the machine, being held at their extremities preferably under tension. To this end each leasing cord is carried over pairs of guide sheaves 78, one sheave being provided for each leasing cord at each end of the machine and having journaled support on the frame members 2. At one end of the machine (left hand end as viewed in Fig. l) each cord is fastened to a holder 79 secured to the upper end of a vertically movable slide rod 80, the latter normally drawn down to produce tension in the cord by means of the coiled spring 81 interposed between a collar 82 on the rod and a guide box 83 through which the rod slides on the machine frame. At its opposite end each leasing cord is secured by wrapping the same about rthe cleat 84 secured to the opposite frame member 2.

During the operation of the machine the leasing cords 75, 76 and 77 are given vertical reciprocatory movement so as to place the cords 75 and 76 on the one hand and the single cord 77 on the other hand alternately above and below the plane of needle action. For this purpose the cords when installed are initially drawn through guiding and holding devices carried by the needle cai'- riage, herein in the form of tubular members, the tubular guide for the cord 7 5 be-A ing represented at 90, that for the cord 7 6 at 91, and that for the cord 77 at 92. These guiding and holding' members are mounted upon vertically reciprocated supports actuated by the following mechanism. The tubular guide 92 is iixedly secured to an arm 93x (Figs. 1 and 2) fastened to the top of a vertically movable slide rod 93, the latter being guided lfor sliding in the upper and lower guide boxes 94 and 95 carried between the two upright needle carriage supporting arms 56 and 62. The slide rod 93 is normally held in its lowermost position by the coiled spring 96 interposed between a collar 97 at the bottom of the rod and the lower side of the guide box 95. It is adapted, however, to be intermittently raised by suitably timed mechanism consisting of the lever arm 98 the forked end of which engages a roll 99 fastened to the side of the slide rod. The lever arm is pivoted at 100 on the needle carriage frame and is connected to the actuating arm 101, the latter carrying a cam roll 102 engaging with the edge cam 103 upon the countershaft 25. This mechanism provides for an up move` ment ofthe slide rod and tubular guide following one retractile movement of the needle and a downward movement of the slide rod and its tubular guide following the next retractile movement.

The tubular guides 90 and 91 for the lease cords 75 and. 76 are similarly moved by slide rods 104 and 105 which rods are connected to move together by the cross head 106. The

rods 104and 105 have sliding movement in.

the guide boxes 94 and 95 and are provided with restoring springs 96 similar to the restoring spring for the rod 93. The cross head 106 is vertically reciprocated by the forked end of the oscillatory lever 107 similar to the lever 98 and operated by a cam 108 on the shaft 25 but timed 180o apart from the timing of the cam 103 so that the tubular guides 90 and 91 move up as the tubular guide 92 moves down, and vice versa.

The result is that the two sets of lease members are caused to bev alternately depressed and elevated at or about the path of the needle between successive thread drawings sothat while positioned as shown in Fig. 5j on one thread drawing, they are subsequently reversed in relation and positioned as shown in Fig. 6 on the next thread drawing. They are then returned to the position shown in Fig. 5 and so on, this resulting in the positioning of successively drawn threads on Opposite sides of the lease cords.

In the described machine the thread as it is drawn between the lease members is also drawn into engagement with suitable means which tend to retain it in approximately its drawn position and prevent the entanglement or displacement of the leased thread. In the described machine this is obtained by pro-r viding a series of closely arranged members, such as the resilient bristles 110 (shown only in Figs. 5 and 6) or the like, the lower ends of which are held fast on the supporting bar 111, the latter, however, being so positioned as to present the row of bristles transverse to the line of needle action. This results in causing the free ends of the threads to be drawn and laid in the bristles where they are held with sufficient certainty to prevent the escape of the leased warp ends. f

The bristle holding support' is omitted in Figs. 1` and 2 for.. the sake of olearness;

In order to move the'leased threads back from the line of action o f theneedle, meansV are provided for' pressing back a drawn thread against the remainder of the already leasedwarp.` This is convenientlyaccomplishe'dherein by giving the tubular guides an endwise thrust movement so that theyv tend /to'thrust or. push'the drawnin threads back out of the line of action of thel needle. Herein thisfendwise thrusting movement is imparted onlytovthe tubular guides 90 and 91, the guide. 92'bein'gy without such move-y ment and this thread-displacing action ta'k-l l ing place" only at each alternate' thread drawing. VIf desired, however, a similar movement couldbe imparted to the thread'- guide 92.

For this purpose -eachr of the tubular guides 90 and 91 is slid'ably mounted in its .holding arm and devices are employed for reciprocatively moving. the `same therein lengthwise the lease cord. The construction" position therein shown. The tubular guidev 91, however, at one'- end hasA the enlarged head 113 ca'rrying'thev laterallyl projectingv pin 114 workin-g in a slotted end 115l of a rock-lever 116':y The latter is pivoted at 117 upon the` lower end ofthe-arm 112, but has a dependingv extension 118- provided with the lateral pin 1119 working in acam guideslot 120. The latter is formed in an adjacent part 121 proj ectingy from the arm 56 and is of such curvilinear form that as the arm 1121` isvertically reciprocated the rock lever 116 and the tubular guide are reciprocatively moved between the full and dotted line positions shown in Fig. 3.

The resultis that as the slide rods 104 and 105 are depressed,the tubular guides 90 and 91 are thrown quickly to the left (as viewed in Fig. 3)-, thrusting. the drawn-in thread (designated at 10 inI Fig. 3) to the left and against the previously leased threads so that the tendency is constantly to thrust the leased threads out of the radius of the needle action.

The machine when operated imparts movement to the needle carriage across the face of the warp, the' needle being reciprocated and the leasing members alternately raised and depressed so that the entire warp is finally drawn and left-in leased condition with reference to the leasing cords.

If desired, compensating feed devices for the warp carriage may be employed'snnrlar to" these' described in the .British lpatent I aforesaid.

-While I have herein shown andl described onel form of the invention, it is to be understood that thek same is not limited to' the d'e-` tails' herein shown, .n'or to' the particular arrangement of operating parts, nor the"L mode of sustainingthe warp with reference to' the operating .elements of the'.r machine-,j
